Hey guys, a strategy for preparing for the quant section of the GMAT. I have done this for a few of the Challenges since I will probably not finish all 25 before my test. Take two or three of the challenges and then only take 30 seconds to answer each question. This should help you formulate a strategy to eliminate wrong answers on really hard questions that you can not solve in less than 3 minutes and then make an educated guess as to the right answer. Even the Q50 and Q51 test takers miss 5-8 questions, so if you can make a very educated guess and get 2-3 more questions right, it will really help your quant score. Even if you guess 25% right, that's better than taking 4 minutes and then still getting a question wrong. Especially if you have those 2-3 extra minutes to work on a problem you know how to do, but need more than 2 minutes to complete.
